ATTENTION AU COMPOSANT AYANT RAPPORT

À LA SÉCURITÉ! LES COMPOSANTS IDENTIFÉS P AR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMA TIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPÉMENTS PUBLIÉS PAR SONY.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following safety checks before releasing the set to the customer.

1. Check the area of your repair for unsoldered or poorly-soldered connections. Check the entire board surface for solder splashes and bridges.

2. Check the interboard wiring to ensure that no wires are "pinched" or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair . Point them out to the customer and recommend their replacement.

4. Look for parts which, through functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement.

5. Check the B+ voltage to see it is at the values specified.

6. Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270˚C during repairing.

• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering or unsoldering.

SERVICE NOTE

1. TO TAKE OUT A CASSETTE WHEN NOT EJECT (FORCE EJECT)

1 Refer to 2-6. to remove the cabinet (L) assembly. 2 Remove the shoulder pad. 3 Remove the CN4300 (2P) of VI-156 board. 4 Remove the CN501 (2P) of VI-156 board. 5 Supply +4.5V from the DC power supply to the cam motor and unload the tape guide. 6 Rotate the idler gear by your finger to the clockwise and remove the tape slack. 7 Supply +4.5V from the DC power supply to the FL motor (Cassette motor) and unload the cassette.

What to do when a user forgets a password

This camcorder has the forced log insertion function. A passw ord is inputted, and this function is set up. When this function was set up, this camcorder doesn’t move if the memory stick which memorize a correct logo isn’t inserted. To release the forced logo function, the correct password must be input. This password is memorized in the IC1105 (EEPROM) on VI-156 board. Therefore, when a user forgets the password, replace the IC1105. This IC1105 memorizes the HRS METER data (Hour meter data: page A, address 00 to 13), too. Therefore, replace the IC1105 in the following order to copy the HRS METER data.

Replacing procedure:

1) Note down the data of page A, address 00 to 13.

2) Replace IC1105 (EEPROM) on VI-156 board.

3) To page A, address 00 to 13, input the data noted down. (Refer to “HRS METER (Hours meter)” of “5-4. SERVICE MODE”)

SELF-DIAGNOSIS FUNCTION

1. SELF-DIAGNOSIS FUNCTION

When problems occur while the unit is operating, the self-diagnosis function starts working, and displays on the viewfinder or LCD screen what to do. This function consists of two display; selfdiagnosis display and service mode display . Details of the self-diagnosis functions are provided in the Instruction manual.

Viewfinder or LCD screen

Indicates the appropriate step to be taken. E.g.

31 ....Reload the tape.

32 ....Tur n o n power again.

1 1

2. SELF-DIAGNOSIS DISPLAY

When problems occur while the unit is operating, the counter of the viewfinder or LCD screen consists of an alphabet and 4-digit numbers, which blinks at 3.2 Hz. This 5-character display indicates the “repaired by:”, “block” in which the problem occurred, and “detailed code” of the problem.

Detailed Code

Refer to page 10. Self-diagnosis Code Table.

3. SERVICE MODE DISPLAY

The service mode display shows up to six self-diagnosis codes shown in the past.

3-1. Display Method

While pressing the “STOP” key , set the PO WER switch from OFF to ON, and continue pressing the “ST OP” key for 5 seconds continuousl y . The service mode will be displayed, and the counter will show the backup No. and the 5-character self-diagnosis codes.

3-2. Switching of Backup No.

By rotating the control dial, past self-diagnosis codes will be shown in order. The backup No. in the [] indicates the order in which the problem occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)

3-3. End of Display

Turning OFF the power supply will end the service mode display.

Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery (BT501) of the cabinet (R) assembly (SW-343 board). When

the cabinet (R) assembly is removed, the “self-diagnosis display” data will be lost by initialization.
